N2 - There are two common sources of light curing used to polymerize composite resins, the LED (Light Emitted Diode) and the QTH (Quartz Tungsten Halogen). This study aimed to evaluate the effect of using different light curing sources on diametral tensile strength of bulk fill composite resins. Three commercial bulk fill composite resins, Tetric N-Ceram Bulk Fill (Ivoclar-Vivadent, Liechtenstein, Germany), Beautifil-Bulk Restorative® (Shofu, Japan), and Filtek ™ Bulk-Fill (3M-ESPE, USA) were used to make disk specimens (6 mm in diameter, 3 mm in thickness) divided into two different polymerized groups (n=10), with LED for 20s and QTH for 40s light curing sources. Diametral tensile strength was tested using a Universal Mechanical Testing Machine (Shimadzu, Japan). Data were analyzed using one way ANOVA and Bonferonni post hoc tests. The results showed that diametral tensile strength mean value of all bulk fill composite resins polymerized using LED source were higher than QTH. There was no statistically difference between the group polymerized using LED and QTH (p ≥ 0.05), except in Filtek ™ Bulk-Fill group (p = 0.012). It can be concluded that different light-curing sources can influence the polimerization effect of Bulk-Fill composite resin in their diametral tensil strength properties.
